Compound

Turns recurring work into reusable skills. Use when a task being done now has been done before in this project, when the user says "make this repeatable", "turn this into a skill", "we'll be doing this again", or at the natural end of a multi-step task that will clearly recur. The rule of thumb - do it once by hand, codify it the second time.

Creates high-quality Claude skills following official best practices. Use when the user asks to create a new skill, improve an existing skill, or needs guidance on skill authoring. Includes guided scoping, proper structure, naming conventions, progressive disclosure patterns, current frontmatter options, and quality validation.

Self-corrects skill and instruction files after a genuine instruction defect is confirmed. Use when Claude errors during skill execution and finds the instruction was at fault, or when the user reports a mistake AND verification confirms the instruction (not the execution) caused it. Applies succinct fixes so a real defect never repeats — without mangling correct instructions on a false alarm.
